Abstract
(EN)
The present invention realizes a welding method with which it is possible to manufacture a joining member having superior toughness. The welding method includes: a first heat-inputting step for forming a joined section in which ferrite-based single-phase stainless steels are joined with each other by inputting heat from a first heat source; and a second heat-inputting step for inputting heat to the joined section from a second heat source so that the cooling speed of the joined section reaches 500ºC/s. or less while the temperature of the joined section is in a range of 1300ºC to 700ºC after the first heat-inputting step and before the temperature of the joined section decreases to 700ºC.

La présente invention réalise un procédé de soudage avec lequel il est possible de fabriquer un élément d'assemblage ayant une ténacité supérieure. Le procédé de soudage comprend: une première étape d'apport de chaleur pour former une section assemblée dans laquelle des aciers inoxydables à phase unique à base de ferrite sont joints les uns aux autres par apport de chaleur provenant d'une première source de chaleur; et une seconde étape d'apport de chaleur pour apporter de la chaleur à la section assemblée à partir d'une seconde source de chaleur de telle sorte que la vitesse de refroidissement de la section assemblée atteint 500°C/s ou moins tandis que la température de la section assemblée est dans une plage de 1300°C à 700°C après la première étape d'apport de chaleur et avant que la température de la section assemblée diminue jusqu'à 700°C.
